DB_ENV->set_encrypt |
#include <db.h>int DB_ENV->set_encrypt(DB_ENV *dbenv, const char *passwd, u_int32_t flags);
int DB_ENV->get_encrypt_flags(DB_ENV *dbenv, u_int32_t *flagsp);
Set the password used by the Berkeley DB library to perform encryption and decryption.
The DB_ENV->set_encrypt method configures a database environment, not only operations performed using the specified DB_ENV handle.
The DB_ENV->set_encrypt method may not be called after the DB_ENV->open method is called. If the database environment already exists when DB_ENV->open is called, the information specified to DB_ENV->set_encrypt must be consistent with the existing environment or an error will be returned.
The DB_ENV->set_encrypt method returns a non-zero error value on failure and 0 on success.
The DB_ENV->set_encrypt method may fail and return one of the following non-zero errors:
The DB_ENV->get_encrypt_flags method returns the encryption flags.
The DB_ENV->get_encrypt_flags method may be called at any time during the life of the application.
The DB_ENV->get_encrypt_flags method returns a non-zero error value on failure and 0 on success.
